Adding references[edit]

References can be added as usual. When using a named reference both on the page and in the infobox, like

<ref name="CRC">{{cite book|...}}</ref>

add the full definition on both pages (best use copy-paste). In the article, they will merge nicely.


Atomic number 119 and above[edit]

When the atomic number is ≥ 119, the miniature periodic table shows an extended version (period 8). See for example {{infobox ununennium}}.
